Correct application

This washer-disinfector is designed

for use with the applications described in these Operating Instructions only. Alterations or conversions to the machine, or using it for purposes other than those for which it was designed, are not permitted and could be dangerous. This machine must only be used for cleaning and disinfecting instruments, medical devices and laboratory equipment if the manufacturer has stated that they are suitable for machine processing. Manufacturer's cleaning and maintenance instructions for instruments etc. must also be observed. Miele cannot be held liable for damage caused by improper or incorrect use or operation of the machine.

This machine is intended for indoor

use only.

This machine is not designed for

use in mobile installations unless a risk assessment of the installation has been carried out by a suitably qualified engineer.

Please pay attention to the following notes to avoid injury and damage.

This machine should be

commissioned and then maintained by a Miele authorised and trained service technician only. A Miele service contract is recommended to ensure compliance with GLP Guidelines and the Medical Devices Directive. Unauthorised repairs could be dangerous, for which the manufacturer cannot be held liable.

Do not install the machine in an area

where there is any danger of explosion or of freezing conditions.

The electrical safety of this machine

can only be guaranteed if connected to a correctly installed earthing system on site. It is most important that this basic safety requirement is present and regularly tested, and where there is any doubt the on-site wiring system should be inspected by a qualified electrician. The manufacturer cannot be held liable for damage or injury caused by the lack of or inadequacy of an effective earthing system (e.g. electric shock).

A damaged or leaking machine

could be dangerous and compromise your safety. Disconnect the machine from the mains immediately and call the Miele Service Department.

Warning and safety instructions

Personnel operating the machine

should be trained regularly. Untrained personnel must not be allowed access to the machine or its controls.

Take care when handling chemical

agents such as cleaning agent, neutralising agent, rinsing agent etc. These may contain irritant or corrosive ingredients. Please follow the manufacturer's safety instructions. Wear protective gloves and goggles. With all chemical agents, the manufacturer's safety instructions and safety data sheets must be observed.

The machine is designed for

operation with water and recommended additive chemical agents only. Organic solvents and flammable liquid agents must not be used in this machine. These could cause an explosion, damage rubber and plastic components in the machine, and cause liquids to leak out of the machine.

The water in the cabinet must not be

used as drinking water.

Be careful when sorting items with

sharp pointed ends and positioning them in the machine that you do not hurt yourself or create a danger for others. Sharp knives etc. should be placed in baskets with the pointed ends facing downwards.

When using this machine in the

higher temperature ranges, be especially careful not to scald or burn yourself or come into contact with irritant substances when opening the door. Where disinfecting agents are used there is a danger of inhaling toxic vapours.

Where there is a risk of toxic or

chemical substances occuring in the suds solution (e.g. aldehyde in the disinfecting agent), it is essential to regularly check door seals and make sure that the steam condensor is functioning correctly. Opening the machine door during a programme interruption carries particular risks in such circumstances.

Should personnel accidentally come

into contact with toxic vapours or chemical agents, follow the emergency instructions given in the manufacturer's safety data sheets.

Mobile units, modules, inserts and

the load must be allowed to cool down before they are unloaded. Any water remaining in containers could still be very hot. Empty them into the wash cabinet before taking them out.

After using the hot air drying unit,

open the door to allow the everything in the cabinet from the load itself to the mobile units, modules and inserts to cool down.

Warning and safety instructions

If the boiler has been programmed

to "BOILER READY", be particularly careful of hot water and steam when opening the door. Danger of burning or scalding. The inlet to the wash cabinet is located, as viewed from the unclean side, underneath the basket runner on the right hand side.

Steam heating is permissible up to a

pressure of 1000 kPa (10 bar). This corresponds to a water steam temperature of 179°C.

Never clean the machine or near

vicinity with a hose or a pressure washer.

The machine must be disconnected

from the mains electricity supply before any maintenance or repair work is carried out. Do not reconnect it until the maintenance or repair work has been successfully completed.

The following points should be observed to assist in maintaining quality standards for processing medical devices and sensitive laboratory glassware, and to avoid injury to patients or damage to equipment.

If the machine is being used for

disinfection in accordance with official regulations on the control of epidemics, the steam condenser and its connections to and from the wash cabinet must be cleaned and disinfected whenever any repairs are carried out or parts replaced.

If it is necessary to interrupt a

programme in exceptional circumstances, this may only be done by authorised personnel.

The standard of cleaning and

disinfection in the disinfection programmes must be routinely confirmed by the user. The process should be validated on a regular basis, and checked against documented control results. Chemical disinfection procedures should also be validated using chemical or bio indicators.

For thermal disinfection, use

temperatures and temperature holding times to achieve the required infection prophylaxis in accordance with current health and safety regulations.

Disinfection programmes which use

a chemical disinfecting agent at moderate temperatures such as 65 °C or lower are not recognised by §18 IfSG for disinfection. They should only be used for items which cannot withstand the higher temperatures used by thermal disinfection. The range of effective disinfection is based on claims made by the producer of the disinfecting agent. Their instructions on handling, use and effectiveness must be observed. The use of chemical disinfection procedures is the responsibility of the operator.

Theatre (OP) shoes should only be

cleaned and disinfected in a machine installed specifically for this purpose.

Warning and safety instructions

Only use chemical agents

formulated for special processes and approved by Miele for use with this machine. Use of unsuitable agents could adversely affect the components of the machine. In the event of any damage or material deterioration please contact your Miele application specialist.

Pre-treatments with cleaning or

disinfecting agents can create foam, as can certain types of soiling and chemical agents. Foam can have an adverse effect on the disinfection and cleaning result.

Foam must not be able to escape

from the wash cabinet. It would hinder the correct functioning of the machine.

Check the process used regularly to

monitor foaming levels.

To avoid the risk of damage to the

machine and any accessories used with it caused by chemical agents, soiling and any reaction between the two please read the notes in "Chemical Processes and Technology".

Where a chemical agent is

recommended on technical application grounds (e.g. a cleaning agent), this does not imply that the manufacturer of the machine accepts liability for the effect of the chemical on the items being cleaned. Please be aware that changes in formulation, storage conditions etc. which may not be publicised by the chemical manufacturer, can have a negative effect on the cleaning result.

When using cleaning agents and

specialised products it is essential that the manufacturer's instructions are followed. Only use the product for the application described by the manufacturer, to avoid any material damage or the occurrence of strong chemical reactions.

In critical applications where very

stringent requirements have to be met, it is strongly recommended that all the relevant factors for the process, such as chemical agents, water quality etc. are discussed with the Miele Application Technology specialists.

If cleaning and rinsing results are

subject to particularly stringent requirements (e.g. chemical analysis, specialised industrial processes etc.), a regular quality control test must be carried out by the user to ensure that the required standards of cleanliness are being achieved.

Mobile units, modules and inserts

should only be used for the purpose they are designed for. Hollow instruments must be thoroughly cleaned, internally and externally.

Empty any containers or utensils

before arranging them in the machine.

Do not allow any remains of acids or

solvents, and in particular hydrochloric acid or chloride solutions, to get into the wash cabinet. Similarly avoid any materials with a corrosive effect. The presence in compounds of any solvents should be minimal (especially those in hazard class A1).

Warning and safety instructions

Ensure that solutions or steam

containing hydrochloric acid do not come into contact with the steel outer casing of the machine, to avoid any corrosion damage.

After carrying out any work on the

mains water system, the water supply system to the washer-disinfector must be vented. Otherwise, the components in the machine may become damaged.

Please follow the advice on

installation in these instructions and the separate Installation Instructions.

Using accessories

Only use genuine Miele original

accessories with this machine. Consult Miele on the type and application of such equipment.

Only use Miele mobile units,

modules and inserts in this machine. Using accessories made by other manufacturers, or making modifications to Miele accessories, can result in unsatisfactory cleaning and disinfecting results, for which Miele cannot be held liable. Any resultant damage would also invalidate the machine guarantee.

Only use chemical agents which

have been approved by their manufacturer for use in the application you are using. The chemical agent manufacturer is responsible for any negative influences on the material the load is made from and for any damage they may cause to the machine.

Symbols on the appliance

Warning: Observe the operating instructions.

Warning: Danger of electric shock.

Disposing of your old machine

Please note that the machine may

have contamination from blood or other bodily fluids in it and must be decontaminated before disposal. For environmental and safety reasons ensure the machine is completely drained of any residual water, chemical residues and cleaning agent. Observe safety regulations and wear safety goggles and gloves. Make the door lock inoperative, and block or disable the door in such a way that children cannot accidentally shut themselves in the cabinet. Then make appropriate arrangements for the safe disposal of the appliance. For tank system machines ensure that any water is emptied out of the tank before it is moved.

The manufacturer cannot be held liable for damage caused by non-compliance with these Warning and Safety instructions.

Intended Use

This washer-disinfector can be used to clean, rinse, disinfect (thermally and chemically) and dry a wide range of reusable medical devices and laboratory equipment. Follow the manufacturer's instructions (according to EN ISO 17664) on how to process their items by machine.

Examples of application areas:

surgical instruments,

–

minimally invasive surgical

–

instruments,

– anaesthetic and intensive care

instruments,

– baby bottles and teats,

– maintenance and waste containers,

– operating theatre shoes,

– laboratory equipment used in

research and development,

–

laboratory equipment used in areas of analysis and specimen taking,

–

laboratory equipment used in micro-biology and biotechnology.

The type of laboratory equipment which can be processed ranges from evaporating dishes to centrifugal test tubes.

Processing medical devices and laboratory equipment by machine achieves reproducible results, and should be used in preference to processing them by hand. Where disinfection is required for the protection of staff and/or patients, a thermal disinfection programme, e.g. the DESIN vario TD programme, should be selected. The parameters for thermal disinfection according to EN ISO 15883-1 (A

concept) vary depending on the disinfection standard required. They are 80 °C (+ 5 °C, - 0 °C) with a 10 min holding time (A

- 0 °C) with a 5 min holding time (A

600) or 90 °C (+ 5 °C,

3000). An A0value of 3000 is suitable for deactivating the HBV virus.

National health and safety regulations regarding disinfection must also be observed.

The cleaning programme as well as any chemical agents must be chosen according to the type of soiling and load being processed. The agents used for processing the products should be selected to suit the level of cleaning required as well as the method of analysis used.

The cleaning result must ensure that instruments can be disinfected correctly, that no residues are left behind, that subsequent sterilisation can be carried out and that the instruments can be used again safely. Medical devices are best processed using the DESIN vario TD programme, or the ORTHOVARIO or OXIVARIO programme where applicable.

The use of a suitable carrier (mobile unit, module, insert etc.) is important to ensure the adequate cleaning of instruments and medical devices. Examples are given in the section "Areas of application".

The washer-disinfector is programmed to carry out the final rinse with mains water or prepared water (e.g. Aqua destillata, pure water, de-ionised water, demineralised water in the quality required by the application). The water quality is of particular importance for applications requiring analytically clean laboratory glassware.

Intended Use

The machine qualifies for the validating of processes in accordance with EN ISO 15883.

The coding of the mobile units and the allocation of programmes in the Profitronic control unit are described in the Programming manual for the washer-disinfector.

small metallic objects or instrument parts attracted to the magnetic strip, in particular to the underside of it. Any metallic objects on the strip can result in the coding being incorrectly read.

Make sure that you code mobile units with side coupling with a track where the sixth magnet is set to 1. Mobile units without side coupling must be coded with a track without the sixth magnet. The magnet strips for PG 8527 / PG 8528 washer-disinfectors must have black magnets.

Areas of application

This washer-disinfector can be fitted with a variety of mobile units, which can be equipped with a variety of modules and inserts depending on the type and shape of items requiring cleaning and disinfection.

Select mobile units, modules and inserts which are appropriate for the application.

Notes on the individual areas of application and examples of loading are given on the following pages.

Before starting a programme you should carry out a visual check on the following:

– Is everything correctly

loaded/connected for cleaning?

– Are the spray arms clean and do

they rotate freely?

–

Are the filters clean? Remove any coarse soiling and clean them properly if necessary.

At the end of each programme:

Carry out a visual check of the load

–

for cleanliness.

Check that all hollow shafted

–

instruments are still securely located on their jets.

Any hollow instruments that have

become disconnected from their adapters during processing must be re-processed.

Check that the lumen of hollow

–

instruments are free of obstruction.

– Check that jets and connectors are

securely held in position in the baskets or inserts.

Protein test

Cleaning results should be subjected to periodic protein tests, e.g. with the Miele test kit.

–

Is the adapter connecting the water supply to the spray arms/jets correctly connected?

–

Are all chemical containers sufficiently filled?

Areas of application

Loading the machine

Arrange the load so that water can

–

access all surfaces. This ensures that it gets properly cleaned.

Do not place items to be cleaned

–

inside other pieces where they may be concealed.

Hollow instruments must be

–

thoroughly cleaned, internally and externally.

Ensure that instruments with long

–

narrow hollow sections can be flushed through properly before placing them in inserts or connecting them to jets.

– Hollow vessels should be inverted

and placed in the correct mobile units, modules and inserts to ensure that water can flow in and out of them unrestricted. A cover can be used to reduce the risk of glass breakage during the wash process.

–

Lightweight items should be secured with a cover net (e.g. an A 6) and small items placed in a mesh tray to prevent them blocking the spray arms or being attracted by the magnetic strip on the automatic mobile unit recognition system.

–

Deep-sided items should be placed at an angle to make sure water runs off them freely.

–

Tall, narrow pieces should be placed in the centre of the baskets. This ensures good water coverage.

Mobile units with an adapter must

–

engage correctly.

Modules must be correctly

–

connected in the mobile unit.

The spray arms must not be blocked

–

by items which are too tall or which hang down in their path. If in doubt, test for free movement by manually rotating the spray arms.

It is advisable to use only instruments

–

made of special application steel which are not susceptible to corrosion.

– Instruments which cannot withstand

high temperatures should be chemically disinfected.

Disposable instruments must not

be put into the machine for processing.

Preparing the load

Empty all containers before loading into the machine (paying particular attention to regulations regarding infectious diseases and epidemics).

Ensure that acids and residual solvents, especially hydrochloric acid or chlorides, cannot get into the wash cabinet.

Unloading instruments

Instruments should be unloaded dry ready for further processing.

Areas of application

Surgical instruments (OP)

Surgical instruments should be stored for as short a time as possible before machine processing. It is best to process surgical instruments using the DES-VAR-TD programme.

The OXIVARIO or ORTHOVARIO programme should be used for instruments where there is a long delay between the time they are used and the time they can be reprocessed. See "Special processes" at the end of this booklet.

Disinfection of surgical instruments and of those used for minimally invasive surgery should preferably take place thermally.

De-ionised water with a conductivity level of ~ 15 ZS/cm (microsiemens per centimeter) should be used for the final rinse whenever possible to ensure no marks are left on the load and to avoid corrosion. If the water used contains more than 100 mg chloride/litre there is danger of corrosion.

OP-containers can be disinfected thermally in the CONTAINER programme, or chemically. If anodised aluminium containers are being processed, de-ionised water must be used for the wash cycles and the final rinse. These containers must not be processed with an alkaline cleaning agent in a 93 °C programme with 10 minutes holding time (according to § 18 IfSG).

Mobile units for surgical instruments and containers are supplied with their own operating instructions.

When processing narrow lumen

instruments e.g. those used for minimally invasive surgery,an

intensive internal cleaning result is imperative. The DES-VAR-TD and OXIVARIO programmes are the only ones which offer a thorough enough level of cleaning for this. It is essential that instruments are loaded as directed and that the cleaning agent used is suitable for the programme and for the sensitive instruments being processed. The final rinse must be carried out using de-ionised water with a conduc tivity level of ~15 ZS/cm (microsiemens per centimeter).

Instruments with very narrow lumen must be manually pre-rinsed where necessary. Follow the instrument manufacturer's instructions on how to handle them.

Areas of application

for opthalmic instruments may only be used in washer-disinfectors which do not have a built-in dispensing system with a flow rate of 465 ml/min.

Plastic fibre cover nets must not

be used in washer-disinfectors which are used to process hollow opthalmic instruments with narrow lumen.

Anaesthetic instruments (AN)

Anaesthetic instruments should be thermally disinfected using the DES-VAR-TD-AN programme.

If this is not possible, they can be processed using a chemical disinfection programme. The water level in the machine should be increased when using a chemical disinfection programme. To establish the effectiveness of disinfection, consult the manufacturer of the disinfecting agent being used.

If the process is not to be followed by sterilisation, the load should be dried completely to avoid the development of water-borne bacteria. A sufficient drying time is, therefore, absolutely essential.

Areas of application

Mobile units for anaesthetic instruments are supplied with their own operating instructions.

Areas of application

Baby bottles (BC)

Baby bottles in E 135 containers can be placed in the two lower levels of mobile unit E 935/1 and then cleaned and disinfected in this washer-disinfector. In addition, E 364 containers with wide-necked teats and E 458 containers with screw-cap teats can be placed in the upper level of the mobile unit.

Ensure the level marker on the

–

bottles is machine-washable.

If there is a delay of 4 hours or more

–

before bottles can be washed, fill them with water to prevent residues from drying on.

Loading in E 935/1 mobile unit

Lower level with4xE135containers

Inserts for baby bottles and teats are supplied with their own operating instructions.

Upper level with3xE135containers

The containers must be arranged so that the two blocked off corners are in the positions marked with crosses, as shown. If bottles were to be placed in these positions, water would not be able to access the inside of the bottles properly and cleaning results would be impaired.

Operating theatre shoes (OS)

Polyurethane operating theatre shoes, and/or insoles should be cleaned and chemically disinfected at 60 °C. These can only be thermally disinfected (using programme SHOE-TD-75/2) if the manufacturer states that they are made of a suitably heat-resistant material.

To establish the effectiveness of chemical disinfecting agents for disinfection consult the manufacturer.

Theatre shoes should be cleaned and disinfected in a machine

installed specifically for this purpose only.

Mobile unit E 975/1 with a suitable insert can be used for this purpose, e.g.

– Insert E 930 for up to shoe size 43

can be placed in the lower level of mobile unit E 975/1,

Areas of application

–

Insert E 931 for up to shoe size 48.

A large amount of fluff can build up in the machine when cleaning theatre shoes. The filters in the wash cabinet should therefore be checked regularly, and cleaned when necessary. See "Cleaning and care".

Areas of application

Laboratory glassware (LG)

Wide-necked laboratory glassware, e.g. beakers, wide-necked Erlenmeyer flasks and Petri dishes, and cylindrical shaped items e.g. test tubes, can be cleaned and rinsed, internally and externally, by the action of the rotating spray arms. They can be arranged in full, half and quarter inserts in an empty mobile unit with spray arms. Narrow-necked items e.g. narrownecked Erlenmeyer flasks, conical flasks, measuring flasks and pipettes, require mobile injector units or injector modules.

The following instructions relate only to basic preparation and loading of glassware.

Loading the machine

– Petri dishes and similar should be

placed in the correct insert with the soiled side facing the centre.

Preparing the load

Empty all glassware before loading

into the machine (paying particular attention to regulations regarding epidemics).

Ensure that acids and residual

solvents, especially hydrochloric acid or chlorides, cannot get into the wash cabinet.

Remove all agar residues from Petri

dishes.

Remove blood clots and residues

from test tubes, etc.

^ Remove all stoppers, corks, labels,

sealing wax residues, etc.

^ Small parts - such as stoppers and

taps - should be secured in suitable basket inserts.

–

Pipettes should be placed with the tip facing downwards.

–

Quarter inserts should be placed as close to the middle of the unit as possible.

–

Glass items must not get in the way of the door opening.

General notes

Problem How to resolve it

If seals, hoses and plastics in the washer-disinfector suffer damage they will not be water-tight and will not function correctly.

Heavy foaming during a programme affects cleaning and rinsing results. Foam escaping from the wash cabinet can cause damage to the washer-disinfector. Cleaning processes cannot be regulated and validated where there has been a build-up of foam..

Corrosion to stainless steel in the wash cabinet and to accessories can give them a different appearance:

– Rust (red marks / discolouration), – black marks / discolouration, – white marks / discolouration (etched

surface).

Corrosive pitting can lead to the washer-disinfector not being water-tight. Depending on application corrosion can influence cleaning and rinsing results (laboratory analysis) or cause corrosion to stainless steel items in the cabinet.

Special processes - OXIVARIO and ORTHOVARIO

Description of the machine

This washer-disinfector can be set up or retro-fitted to use the OXIVARIO process by adding two additional dispenser pumps together with a buffer tank for hydrogen peroxide solution (H

). The DOS 2 dispenser is used

2O2

for the H

To use the ORTHOVARIO process the DOS 4 dispensing system has to be replaced by a dispenser pump for a tenside based cleaning agent.

The OXIVARIO, OXIVARIO PLUS and ORTHOVARIO programmes are available for these requirements.

The OXIVARIO process releases active oxygen under alkaline conditions. The cleaning agent used must be tenside free and have a pH value of between 11 and 11.5.

The ORTHOVARIO process uses a special tenside based cleaning agent in the first cleaning phase and then releases active oxygen in the second phase with a pH value of between 10.0 and 11.0 and a slightly higher temperature of 65 °C.

2O2

solution.

It is also suitable for antiseptic circumstances.

The cleaning process is gentle enough for instruments used in minimally invasive surgery, including fibre optics, where the manufacturer has declared that they are suitable for processing with an alkaline cleaning agent.

It is not suitable for anodised aluminium. Be aware that items made from alloys containing titanium such as some implants, do not always state the material's compatibility. If in doubt please consult the manufacturer of the item.

The ORTHOVARIO procedure is suitable for processing aluminium instruments which are sensitive to alkalines. It is particularly suitable for orthopaedic instruments including motor systems.

Because of its oxidising effect it must not be used for titanium implants, and in particular colour coded ones.

Areas of application

The OXIVARIO procedure has an alkaline main wash making it particularly suitable for the processing of surgical instruments where existing procedures are not satisfactory. It is particularly suitable for instruments such as those used in high frequency surgery, orthopaedic surgery as well as for instruments which have dried out because of the length of time between using them and reprocessing them.

Due to the high efficacy of the Oxivario and Orthovario processes, it is important to lubricate joints and contact parts on instruments pre-sterilisation. Please refer to the instrument manufacturer for guidance.
